Before You Cleanse
Colon cleansing is a common alternative health practice, but what is the evidence for it? Doctors say the answer is, essentially, none.
The theory behind colonic irrigation is the now-discredited belief that the intestines are the seat of most illnesses. The procedure involves diuretics and laxatives, followed by flushing the intestine with water. The medical basis was debunked a century ago, and the chemicals involved are unregulated.
Although there is no verified benefit to colonic irrigation, medical experts say there is a great deal of risk. Side effects range from cramping and nausea to kidney failure and liver toxicity. In addition, practitioners of colonic therapy aren't typically professionally trained, poorly sterilized equipment can cause infections and certifying boards often require little more than a high-school diploma.
Colonic irrigation practitioners often exaggerate the dangers of the "toxins" they claim to treat. The best way to maintain good heath is with a balanced diet, regular exercise, and a good night's sleep.
